Before the construction of the motorway, this was an important pass between St-Ursanne and Courgenay; now it's quieter and therefore more attractive to road cyclists. The pass itself is unspectacular—apart from the sign with the altitude and an information board about visiting the 2012 Tour de France, there's little to justify a longer stay.

There are several Cols de la Croix in the French-speaking part of Switzerland, including the one above the beautiful village of Saint Ursanne. While the climb to the 789-meter-high pass doesn't cover the same elevation gain as those in Valais, steep ramps are sure to make you sweat.

Not a spectacular climb. But a beautiful rural area.
